You can think of work as a transfer of energy.

3. Kinetic energy Energy of motion; any moving object has kinetic energy.

Roller coaster car traveling
down hill.
Throwing a ball
Jumping on a trampoline

4. Potential energy
Stored energy; energy an object has due to its position or its shape.
Examples:
Rollercoaster car on
top of hill

Bow and arrow

5. Mechanical energy
Energy possessed by an object due to its motion or position; object’s combined potential and kinetic energy.
Examples:
A thrown baseball
Windmills

6. Law of conservation of energy
Total amount of energy never changes; no matter how energy is transferred or transformed, all of the energy is still present somewhere in one form or another.
